Overview

The purpose of this page is to review SPCC refined smoothed analytic segments and compare them to version 1.0. This comparison report is still in development, and further maps and reports will be added as they are developed.

This website compares version 2.0v2 to version 1.0. Version 1.0 represents the future version of SPCC and provides a baseline for comparison. Version 2.0v2 includes updated data layers where new data is available in addition to refined measures for evaluating intersection density, building placement, and land use diversity.

SPCC 1.0 and SPCC 2.0v2 Mapping: Refined Smoothed Segments

Note: The Directional Change map only shows changes between detailed analytic classes C1-C6.

SPCC 1.0 vs. SPCC 2.0v2

Cross tabulation of SPCC 1.0 versus SPCC 2.0v2 by Linear Feet

The table below provides a tabular comparison of SPCC refined smoothed analytic versions 1.0 to 2.0v2c. The rows represent linear feet of each classification under SPCC 1.0, and the columns represent liner feet per classification under SPCC 2.0v2.
